Description

Title of the invention: Fluid connection system Field of invention

[0001] The present invention relates to a fluid connection system for a cleaning system of a car and a vehicle, in particular a car, comprising a tube, a nozzle and the fluid connection system according to the invention. TECHNOLOGICAL BACKGROUND OF THE INVENTION

[0002] A fluid connection system for a car cleaning system is used to connect several tubes by the fluid connection system. In this case, a correct connection is essential for the operation of the cleaning system. If the tubes are connected incorrectly, the cleaning system may not work or, in the worst case, be damaged, because the wrong fluid and / or pressure is applied to the tubes.

[0003] It is therefore important to ensure that the fittings are correctly connected. In the prior art, different diameters are used for the tube and the connecting piece. US 7,472,929 B2 discloses a system comprising two connecting pieces having different outer diameters. Therefore, the tubes connected to the two connecting pieces also have different inner diameters. In this way, it is possible to ensure that the tubes are correctly connected to the connecting pieces.

[0004] Document US 7,472,929 B2 discloses a system comprising at least two connecting pieces. Here, the outer diameter of each connecting piece varies along the length of the connecting piece. Thus, tubes of different inner diameters can be connected to the connecting pieces.

[0005] However, in the prior art, tubes with different inner diameters are required. Due to the different diameters, the flow rate, pressure and / or volumetric flow rate vary. Therefore, known systems make it difficult to regulate a uniform fluid flow rate in all tubes.

[0006] Furthermore, the inner diameters of the tubes vary only slightly, so that errors regularly occur when assembling the tubes. Even if the tubes and connecting parts have different diameters, a bad connection can still be established by applying too much force to the tube during connection. The fluid connection system then does not work or can be damaged.

[0007] Based on this prior art, the object of the invention is to provide a durable and cost-effective fluid connection system, which is an error-proof system and easy to assemble, while ensuring the function of the fluid connection system and uniform fluid flow. BRIEF DESCRIPTION OF THE INVENTION

[0008] According to a first aspect of the invention, the aforementioned object is solved by a fluid connection system for a cleaning system of a car, wherein the fluid connection system comprises at least two connections, wherein each of the at least two connections comprises a male connector and a female connector, wherein for each of the at least two connections the male connector comprises an outlet opening and the female connector comprises an inlet opening, wherein for each of the at least two connections the male connector and the female connector are configured to fluidically connect the outlet opening to the inlet opening in the assembled state, wherein for each of the at least two connections the length of the male connector is adapted to the length of the female connector, wherein the length differs for each of the at least two connections.

[0009] The fluid connection system has the advantage of being error-proof, so that the operation of the fluid connection system is ensured. Therefore, the fluid connection system offers good durability. In addition, the fluid connection system is easy to assemble since only the correct male connector and female connector can be connected due to their identical length. In addition, the fluid connection system allows for uniform flow of fluids. In addition, the fluid connection system can be cost-effective.

[0010] The fluid connection system may be a system for supplying fluid from a central supply to different fluid outlets. The different fluid outlets may be, for example, nozzles of a cleaning system. The fluid connection system may be configured to provide a uniform fluid flow through all of the tubes. For example, the cleaning system may be configured to clean a windshield, a sensor, and / or a headlight.

[0011] The at least two connections may be a fluid connection, for example of tubes or a tube and a distributor. The at least two connections may be configured to fluidly connect, for example, tubes or a tube and a distributor.

[0012] The male connector may have a protruding portion that can be inserted into a receiving space of the female connector. The shape of the male connector may be adapted to the shape of the female connector.

[0013] The outlet opening may be configured to discharge a fluid that may be within the fluid connection system. The inlet opening may be configured to receive a fluid, which may be within the system fluid connection. The outlet opening and the inlet opening may have the same cross-section. The outlet opening may be arranged at the end of the male connector. The inlet opening may be arranged at a distance from one end of the female connector. In particular, the inlet opening may be arranged at a distance from an end of the female connector into which the male connector can be inserted.

[0014] The male connector and the female connector are configured to fluidly connect the outlet opening to the inlet opening in an assembled state. The assembled state may be the state in which the male connector and the female connector can be connected to each other, in particular in a manner that provides a form-fit and / or force-fit connection. The outlet opening and the inlet opening may be fluidly connected if fluid can be transferred without loss of a portion of the fluid from the outlet opening to the inlet opening.

[0015] The length of the male connector is adapted to the length of the female connector. The length of the male connector may be the protruding portion of the male connector that can be inserted into the female connector, particularly into a receiving space of the female connector. The length of the female connector may be the length of the receiving space of the female connector into which the male connector can be inserted. The male connector and the female connector may be configured to lock each other only if the length of the male connector and the female connector is the same.

[0016] The length differs for each of the at least two connections. For example, the length may be the same for a single male connector and a single female connector. The length of the male connector of the first connection of the at least two connections may be different from the length of the male connector of the second connector of the at least two connections and the length of the female connector of the second connector of the at least two connections. The different length for each of the at least two connections may mean that the lengths of the male connectors of the at least two connections may be different for each of the at least two connections, and that the lengths of the female connectors of the at least two connections may be different for each of the at least two connections.

[0017] For example, the fluidic connection system may include at least two connections, wherein the first connection of the at least two connections may include a first male connector and a first female connector, wherein the first male connector may be configured to be fluidically connected to the first female connector, wherein the first male connector may include an outlet opening and at least one limiting element, wherein the at least one restricting element may be arranged in the flow direction before the outlet opening, wherein the first female connector may comprise an inlet opening and at least one restricting means, wherein at least one restricting means may be arranged in the flow direction before the inlet opening, wherein, in the assembled state, at least one restricting means may abut at least one restricting element, wherein, in the assembled state, the outlet opening may be connected to the inlet opening, and wherein the second connection of the at least two connections may comprise a second male connector and a second female connector, wherein the second male connector may be configured to be fluidically connected to the second female connector, wherein the second male connector may comprise an outlet opening and at least one restricting element,wherein at least one limiting element may be arranged in the flow direction before the outlet opening, wherein the second female connector may comprise an inlet opening and at least one restricting means, wherein at least one restricting means may be arranged in the flow direction before the inlet opening, wherein, in the assembled state, the at least one restricting means may abut against the at least one limiting element, wherein, in the assembled state, the outlet opening may be connected to the inlet opening, wherein the length between the at least one limiting element and the outlet opening may correspond to the distance between the at least one restricting means and the inlet opening, and wherein the length of the first of the at least two connections may differ from the length of the second of the at least two connections.

[0018] In one embodiment, the male connector of one of the at least two connections can only mate with the female connector of the same of the at least two connections.

[0019] In this way, the fluid connection system can be error-proof, so that the function of the fluid connection system can be ensured. In addition, the fluid connection system can be easy to assemble since only the male connector and the female connector can be properly connected. In addition, the fluid connection system can ensure uniform flow of fluids.

[0020] The single connection and the same connection may be the same connection. The single connection may be one of at least two connections. In particular, all the connections may be different from each other, since they all have a different length, so that the single connection may be one of at least two connections. For the same connection, the length of the male connector may correspond to the length of the female connector.

[0021] In one embodiment, the male connector may comprise at least one limiting element, wherein the limiting element may be spaced from the outlet opening, wherein the female connector may comprise at least one restriction means, wherein the restriction means may be spaced from the inlet opening, wherein the length may be the distance between the limiting element and the outlet opening and between the restriction means and the inlet opening.

[0022] In this way, the fluid connection system can be error-proof, so that the function of the fluid connection system can be ensured. In addition, the fluid connection system can be easy to assemble since only the male connector and the female connector can be properly connected by means of at least one limiting member and at least one restricting member. In addition, the fluid connection system can ensure uniform flow of fluids.

[0023] The at least one limiting element may be configured to limit the movement of the male connector in the female connector, in particular in the receiving space of the female connector. The movement of the male connector in the female connector may be in the direction of the flow of the fluid of the fluid connection system. To limit the movement of the male connector, at least one limiting element may have a contact surface that can interact with the female connector, in particular the at least one restriction means. The at least one limiting element may be in contact with the surface of the female connector so as to limit the movement of the male connector in the female connector, in particular in the receiving space of the female connector.

[0024] The male connector may comprise at least one limiting element may mean that the male connectors of the at least two connections may each comprise at least one limiting element.

[0025] The female connector may comprise at least one restriction means may mean that the female connector of at least one of the at least two connections may comprise at least one restriction means.

[0026] The length may be the distance between the at least one limiting element and the outlet opening and between the at least one restriction means and the inlet opening. The length of each of the male connectors of the at least two connections may be the distance between the at least one limiting element and the outlet opening, and the length of the female connectors of at least one of the at least two connections may be the distance between the at least one restriction means and the inlet opening.

[0027] The at least one restriction means may be configured to limit the movement of the male connector in the female connector, in particular in the receiving space of the female connector. The movement of the male connector in the female connector may be along the direction of flow of the fluid of the connection system. fluidics. To limit the movement of the male connector, the at least one restriction means may have a contact plane that can interact with the male connector, in particular with the at least one limiting element. The at least one restriction means may be in contact with the surface of the male connector so as to limit the movement of the male connector in the female connector, in particular in the receiving space of the female connector.

[0028] The at least one limiting element and the at least one restricting means may be configured to restrict movement of the male connector in the female connector, particularly in the receiving space of the female connector, in a form-locking manner. For example, the contact surface of the at least one limiting element may contact the contact plane of the at least one restricting means to restrict movement of the male connector in the female connector. For example, the contact surface may face the outlet opening and / or the contact plane may face the inlet opening.

[0029] The at least one limiting element may be spaced apart from the outlet opening. For example, the at least one limiting element may be arranged in the flow direction before the outlet opening. In particular, the at least one limiting element and the outlet opening may be separate.

[0030] The at least one restriction means may be spaced from the inlet opening. For example, the at least one restriction means may be arranged in the flow direction before the inlet opening. In particular, the at least one restriction means and the inlet opening may be separate.

[0031] In one embodiment, the at least one limiting element may have an outer diameter, the outer diameter of the at least one limiting element being different for each male connector of the at least two connections, the female connector of at least one of the at least two connections being able to comprise an insertion space, the insertion space being able to be arranged between the at least one limiting means and an open end of the female connector of at least one of the at least two connections, the insertion space being able to have an inner diameter, the inner diameter of the insertion space of the female connector of at least one of the two connections being able to be identical to the single outer diameter of the at least one limiting element of the male connector of the same connection of the at least two connections.

[0032] In doing so, the fluid connection system can have the advantage of being error-proof, thereby ensuring the operation of the fluid connection system. Thus, good durability of the fluid connection system can be ensured. In addition, the fluid connection system can be easy to assemble since it only requires connecting the correct male and female connectors. In addition, the Fluidic Connection System can be cost-effective.

[0033] The outer diameter of the at least one limiting element may be the spatial extension of the at least one limiting element transversely, in particular perpendicularly, to the direction of flow of the fluid. The outer diameter of at least one limiting element may be the spatial extension of at least one limiting element transversely, in particular perpendicularly, to the direction of connection between the male connector and the female connector. The outer diameter may be the distance between two outer edges of the at least one limiting element connected by the center of the at least one limiting element.

[0034] The insertion space may be an area into which a portion of the male connector is inserted. The insertion space may be part of the receiving space. The insertion space may be disposed between the at least one restriction means and the open end. The at least one restriction means may be the restriction means that interacts with the at least one limiting element. The open end may be the open end of the female connector into which the male connector may be inserted.

[0035] The inner diameter of the insertion space may be the spatial extension of the insertion space transverse, in particular perpendicular, to the direction of flow of the fluid. The inner diameter of the insertion space may be the spatial extension of the insertion space transverse, in particular perpendicular, to the direction of connection of the male connector with the female connector. The inner diameter may be the distance between two inner walls of the insertion space connected by the center of the insertion space.

[0036] The inner diameter of the insertion space of the female connector of at least one of the at least two connections may be the same as the only outer diameter of at least one limiting element of the male connector of the same connection of the at least two connections. Therefore, only the at least one limiting element having the same outer diameter as the inner diameter may be inserted into the insertion space and thus into the female connector. The inner diameter and the outer diameter may be identical, which allows the male connector to be inserted into the female connector.

[0037] In one embodiment, the at least one restriction means may abut the at least one limiting element in the assembled state, and / or the outlet opening may be adjacent the inlet opening in the assembled state.

[0038] If the at least one restriction means can abut against the at least one limiting element in the assembled state, the connection of the male connector and the female connector can be very simple. Thus, the assembly of the connection system Fluidics can be very easy. In addition, assembly can be error-proof, since correct assembly can be easily verified.

[0039] If the outlet opening can be adjacent to the inlet opening in the assembled state, the fluid connection system can provide a uniform fluid flow.

[0040] If the at least one restriction means can abut against the at least one limiting element in the assembled state, and if the outlet opening can be adjacent to the inlet opening in the assembled state, the fluid connection system can be very efficient since a correct assembly can be ensured and, at the same time, a good fluid connection can be guaranteed. Furthermore, since the at least one restriction means can abut against the at least one limiting element in the assembled state, and the outlet opening can be adjacent to the inlet opening in the assembled state, the fluid connection system can be very well aligned and very reliable.

[0041] The at least one restriction means may abut against the at least one limiting element in the assembled state. Therefore, the contact surface of the at least one limiting element may contact the contact plane of the at least one restriction means to limit movement of the male connector in the female connector.

[0042] The outlet opening may be adjacent to the inlet opening in the assembled state. Thus, the outlet opening may be so close to the inlet opening that good flow of fluid from the outlet opening to the inlet opening can be ensured. This may mean that there is no loss of fluid.

[0043] In one embodiment, the inner diameter of the outlet opening and the inner diameter of the inlet opening may be identical, in particular for all at least two connections.

[0044] In doing so, the fluid flow can be uniform within the fluid connection system, thereby increasing the efficiency of the fluid connection system due to uniform fluid flow. If the inner diameter of the outlet opening and the inner diameter of the inlet opening can be the same for at least two connections, the fluid flow can be uniform within the entire fluid connection system, so that the efficiency of the fluid connection system can be further improved due to uniform fluid flow.

[0045] The inner diameter may be the length of a straight line passing through the center of the outlet opening from one side of the outlet opening to an opposite side of the outlet opening. The inner diameter may be the length of a straight line passing through the center of the inlet opening from one side of the inlet opening to an opposite side of the inlet opening. If the inner diameter of the outlet opening and the inner diameter of the inlet opening may be the same for all of the at least two connections, each outlet opening of all male connectors of the fluid connection system and each inlet opening of all female connectors of the fluid connection system may be identical.

[0046] In one embodiment, the male connector may be removably connected to the female connector, and / or the male connector may be connected to the female connector in a form-locking and / or force-locking manner.

[0047] If the male connector can be removably connected to the female connector, the parts of the fluid connection system can be easily replaced. Thus, the durability of the fluid connection system can be improved.

[0048] If the male connector can be connected to the female connector by form-locking and / or force-locking, assembly can be very easy.

[0049] If the male connector can be removably connected to the female connector, and if the male connector can be connected to the female connector by form locking and / or force locking, the connection of the female connector can be very durable and easy to close and open. Therefore, the assembly and disassembly of the fluid connection system can be very easy, thereby improving the durability.

[0050] The male connector can be removably connected to the female connector such that the male connector can be detached from the female connector non-destructively.

[0051] In one embodiment, the female connector may comprise an opening extending at least partially from the inlet opening to the at least one restriction means, wherein in particular a retaining element may be arranged within the opening, wherein in particular the retaining element may fix, in particular in a form-locking and / or force-locking manner, the male connector to the female connector in the assembled state.

[0052] If the female connector may comprise an opening extending at least partially from the inlet opening to the at least one restriction means, the female connector may be lightweight so that handling and therefore assembly of the fluid connection system may be very easy.

[0053] If the female connector can comprise an opening extending at least partially from the inlet opening to the at least one restriction means, wherein in particular a retaining element can be arranged inside the opening, wherein in particular the retaining element can fix, in particular in a form-locking and / or force-locking manner, the male connector to the female connector in the assembled state, the male connector can be easily connected to the female connector. Furthermore, the retaining element can be placed inside the opening so as to be visible. Thus, the connection of the male connector to the female connector can be checked. In addition, the retaining element can be used for assembly. This simplifies the assembly of the fluid connection system.

[0054] The opening may be a material recess inside the female connector. The opening may connect the inside of the female connector to the outside of the female connector. The opening may extend at least partially from the inlet opening to the at least one restriction means. Thus, the at least one opening may be arranged before the inlet opening such that the flow of the fluid is not impeded by the opening. In particular, in the assembled state, the outlet opening of the male connector may be placed behind the opening in the direction of flow.

[0055] The retaining element may be disposed within the opening. In particular, the retaining element may be disposed within two openings, the two openings being disposed on opposite sides of the female connector, the retaining element may have two activation planes, the activation planes may be disposed within the two openings, the retaining element may have two arcs, each arc may connect one end of one activation plane to one end of the other activation plane, the arcs may be configured to move outwardly of the female connector, when the two activation planes may be pressed into the female connector.

[0056] For example, the two arcs may each have a holding means, the male connector may have two receiving means, the holding means may interact with the receiving means to secure the male connector in the female connector in the assembled state.

[0057] In one embodiment, the female connector may include a sealing element, particularly a D-ring, wherein the sealing element may be disposed at the inlet opening.

[0058] If the female connector can include a seal, the fluid flow between the male connector and the female connector can be improved, so that the fluid connection system can provide very good fluid flow. If the sealing element is a D-ring, the connection between the outlet opening and the inlet opening can be impermeable, thereby further improving the flow of the fluid connection system.

[0059] The sealing element may be, for example, an O-ring. A D-ring may be shaped like a D, in which the flat surface may be pressed against the surface of the female connector and the arch may be oriented toward the center of the female connector.

[0060] In one embodiment, the male connector may be monolithic.

[0061] In this way, the male connector can be very durable, and the male connector can be produced very cost-effectively. Thus, the fluid connection system can be very durable and cost-effective.

[0062] Monolithic can mean that the male connector can be manufactured in one piece.

[0063] In one embodiment, the fluid connection system may include a valve, wherein the valve may be fluidly connected to the at least two connections.

[0064] In doing so, the fluid connection system can provide a very uniform fluid flow rate. The valve can be configured to regulate the fluid flow rate through each of the at least two connections. The valve can be placed before the connections in the direction of flow.

[0065] In one embodiment, the Fluid Connection System may be designed for a fluid pressure of 5 bar, in particular 8 bar, up to 12 bar.

[0066] In doing so, the fluid connection system can provide a very good fluid flow rate. For example, the fluid flow rate may be sufficient for a car's cleaning system.

[0067] In this way, the fluid connection system can have the advantage of being error-proof, so that the operation of the fluid connection system can be ensured. The fluid connection system can therefore provide good durability. In addition, the fluid connection system can be easy to assemble since only the male connector and the female connector can be connected due to their identical length. In addition, the fluid connection system can ensure uniform flow of fluids. In addition, the fluid connection system can be cost-effective.

[0068] In one embodiment, the male connector and the female connector of each of the at least two connections may have corresponding rotational symmetry.

[0069] In doing so, the correct assembly can be further improved and simplified, since another error-proof system can be added. Therefore, the operation of the fluid connection system can be ensured. The fluid connection system can therefore have good durability. In addition, the fluid connection system can be easy to assemble since only the male connector and the female connector can be connected with the same rotational symmetry. Furthermore, the fluid connection system can be cost-effective since additional rotational symmetry can be produced at a lower cost.

[0070] Rotational symmetry may be the property that a shape can have when it is identical after being rotated a partial turn. The degree of rotational symmetry of the male connector and the female connector may be the number of distinct orientations in which they can have exactly the same appearance for each rotation.

[0071] In one embodiment, the rotational symmetry may be achieved by a rotationally symmetrical cross-section, the rotationally symmetrical cross-section which can in particular be achieved by a notch and / or a polygonal cross-section.

[0072] In this way, correct assembly can be facilitated by adding another error-proof system. Therefore, the function of the fluid connection system can be ensured. The fluid connection system can therefore provide good durability. In addition, the fluid connection system can be easy to assemble since only the male connector and the female connector can be connected with the same rotational symmetry. Furthermore, the fluid connection system can be cost-effective since additional rotational symmetry can be produced at a lower cost.

[0073] The rotationally symmetrical cross-section may be the cross-section of the male connector and the female connector perpendicular to the direction of flow. The polygonal cross-section may be, for example, in the shape of a rectangle, a triangle, or a square, which may correspond to a degree of rotational symmetry of two, three, or four, respectively. A notch provides a degree of rotational symmetry of one.

[0074] In one embodiment, the fluid connection system may comprise three connections.

[0075] The fluid connection system has the advantage of being error-proof, which can ensure its operation. Therefore, the fluid connection system can provide good durability. In addition, the fluid connection system can be easy to assemble since only the male connector and the female connector can be connected due to their identical length. In addition, the fluid connection system can ensure uniform flow of fluids. Furthermore, the fluid connection system can be cost-effective. In particular, with three connections, it is possible to ensure very good fluid supply, for example for a car cleaning system.

[0076] According to a second aspect of the invention, the aforementioned object is solved by a vehicle, in particular a car, comprising a tube, a nozzle and the fluid connection system according to the invention, in which the tube, the nozzle and the fluid connection system are fluidically connected.

[0077] The fluid connection system has the advantage of being error-proof, so that the operation of the fluid connection system is ensured. Therefore, the fluid connection system, and thus the vehicle, offers good durability. In addition, the fluid connection system, and thus the vehicle, is easy to assemble since only the male connector and the female connector can be connected due to their identical length. In addition, the fluid connection system allows for uniform flow of fluids. Therefore, the vehicle provides very good fluid flow distribution. In addition, the fluid connection system and therefore the vehicle are cost-effective.

[0078] According to a third aspect of the invention, the aforementioned object is solved by the use of a fluidic connection system according to the invention for a cleaning system.
